Question

Rank the elements in each of the following sets in order of increasing atomic radius (Use the appropriate <-> symbol to separate substances in the lot.) (a) , cherad Help X.X (b), A C chemPad Help Greek

Answer 1

groupie group from up to down the atomic radius increases. (a) Li, Na, (s and H are the same group-1. We know that in a Now (s is mostly down thais Na, Li and H. so (s has higher atomic radius and h has lowest atomic radius: so the increasing order of atomic radius .is H <li < Na < cs <cs. (6.) Si Ar, Al, el are in the same period: We know that of a period from left right the atomic Jadius decreases. Ar is mostly left than ce, siand Al Al has highest atomic radius and Ar has lowest atonne radiis. order of atonne radius is Ar:<e < si < Al to Now, So so the increasing a CS scanned with CamScanner.
